simple way to create node http server

// @ts-check
const Koa = require('koa');
const Router = require('koa-router');
const bodyParser = require('koa-bodyparser');
const cors = require('@koa/cors');
const bAuth = require('./basic_auth');

const { request, deep_equal } = require('../commons');
const { set_authorization_middleware } = require('./authorization');
const { get_routing_model } = require('../routing_templates');

module.exports = function (model) {
  const app = new Koa();
  const { debug, jsonLimit = '150mb' } = model;

  function require_module_from_string(src, filename = '') {
    const Module = module.constructor;
    // @ts-ignore
    const mod = new Module();
    mod._compile(src, filename);
    return mod.exports;
  }

  const routs = require_module_from_string(get_routing_model(model))(Router, request, deep_equal, bAuth);

  app.use(bodyParser({ jsonLimit: jsonLimit }));

  // if fake server model contains authorization property
  // next execution will set koa-bearer-token middleware
  // @ts-ignore
  set_authorization_middleware(app, model);
  app.use(cors());

  if (debug) {
    const logger = require('koa-logger');
    app.use(logger());
  }

  app.use(routs);

  return {
    app,
  };
};
